Al'Quraan

The woman and the man guilty of illegal sexual intercourse, flog each of them with a hundred stripes. Let not pity withhold you in their case, in a punishment prescribed by Allah, if you believe in Allah and the Last Day. And let a party of the believers witness their punishment. (This punishment is for unmarried persons guilty of the above crime but if married persons commit it, the punishment is to stone them to death, according to Allah's Law).

Al'Quraan Surah Noor

Prophet Mohammad PBUH

Narrated: Abu Huraira (R.A) that a man said to the Prophet, sallallahu 'alayhi wasallam: "Advise me! "The Prophet (PBUH) said, "Do not become angry and furious." The man asked (the same) again and again, and the Prophet said in each case, "Do not become angry and furious." [Al-Bukhari; Vol. 8 No. 137]
